Characteristics and genesis of hypothermal uranium and thorium mineralization in Luzong basin :Evidence from the scientific drilling ZK01 at Zhuanqiao. Acta Petrologica Sinica ，30 (4 ): 1017 － 1030 Abstract Scientific deep drilling named ZK01 of Zhuanqiao lies in the centre of Luzong. Based on a series of work ，uranium and thorium mineralization is in syenites and monzonites (1500 ～ 1900m)of ZK01 associated with albitization ，feldspar ，tourmaline and anhydrite. The alteration and mineralization can be divided into five stages ，green-tourmaline + feldspar + anhydrite at stage ，pink- Ⅰ tourmaline + anhydrite + uranium-thorium mineralization at stage Ⅱ，black-tourmaline + anhydrite + uranium-thorium mineralization at stage Ⅲ，anhydrite + copper + pyrite at stage Ⅳ and gypsum + calcite + quartz at stage V. Uranium and thorium mineralization are occurred as brannerite ，uraninite and ura
